We need a president who is looking for the next George Patton in the Army, the next Bull Halsey in the Navy, the next Chesty Puller in the Marine Corps and the next Curtis Lemay in the Air Force. The chain of command, from the CIC down to the front line commander needs to be a pussy-free zone.
Neither Lincoln nor Franklin Roosevelt were reluctant about firing or demoting incompetent generals. Not that I wish another Civil War or World War II on America, but I believe Trump is of a like mind as these two wartime Presidents with respect of requiring military competence. Also, Lincoln and Roosevelt did not tie the hands of their generals or admirals.
